device-to-stream-units

Arguments:
stream position-or-box

Converts a position or box that is in device units (directly relative
to the physical interior upper left corner of the device (typically a
window) specified by stream) so that it is in stream units (offset
from its position relative to the physical interior upper left corner
of window according to the scroll position and origin of stream).

Destructively modifies the position-or-box argument.

In earlier releases, this function was named
window-to-stream-units. The old name can be
used for backward compatibility.
